Landkreuzer P. 1500 Monster Would Have Been The Largest Tank Ever Built.

Landkreuzer P. 1500 Monster


Few realize that Adolph Hitler’s war machine began designing a tank fifteen times as large as a Panzer Mk 5, and carry a gun that fired an 800mm round as far as 20 miles. The Krupp 800mm projectile is the largest ballistic fired projectile in history. Each shell was over 20,000 pounds.

.Technically of course this would not have been a tank at all but a self-propelled howitzer. For some reason, these two very different kinds of vehicles were lumped together as tanks. But the point here is that Hitler spent an enormous sum of money developing one weapon system after another and in a short space of time. Of course, Germany had some of the top engineering schools in Europe, and there as money after Hitler came to power for this sort of research.


The Russians and the Americans and the British all had robust experimental weapons programs during the Second World War. Even the French were developing a gigantic tank called the FCM f1. It was supposed to have 6 machine guns and over 100mm of armor plating. The concept of giant tanks never really took off beyond the labs and machine shops. They were just too big to transport, required too many personnel to operate and used too much fuel. It was not imagination that killed off the super tanks.  Logistics did.

I absolutely love your blog and find the majority of your post’s to be exactly I’m looking for.
Does one offer guest writers to write content for yourself?

The last picture is of the largest railway gun that was made. See this blogpost:
And the P1500 would be smaller than the railwaygun, with a smaller caliber gun. I think they wanted to put one of the 15inch turrets of the Scharnhorst on it.
Anf again, it would have been a very big artillery target, not to mention being bombed and rocketted into oblivion by tactical and strategical bombers.
